M Af April 3, 1956 United States This inventionrelates to a cigarette lighter liller valve and more particularly to anattachment for a cigarette lighter whereby the packing in the lightermay be saturated with fluid in a convenient manner.

Another object of this invention is to provide a cigarette lighterfiller valve having a check valve therein normally urged to its closedposition for restricting the llow of Huid from the lighter and whichvalve is urged to an open position by the pressure of uid from acontainer.

Another object of this invention is to provide a cigarette lighterfiller valve for attachment to cigarette lighters which includes novelmeans for retaining a spare flint in the lighter.

A further object is to provide a cigarette lighter liller valve having afluid receiving opening countersunk at its entrance and a nozzle forengagement with the countersunk portion for attachment on the containerto reduce to a minimum the fluid wasted during the lilling of a lighter.

A yet further object of this invention is to provide a cigarette lighterfiller valve which is simple and practical in construction, strong andreliable in use, small and compact in structure and otherwise welladapted for the purposes for which the same is intended.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure l is a side elevational View partly in section showing acigarette lighter with the improved iller valve mounted thereon and witha container connected thereto for supplying fluid to the lighter;

Figure 2 is an enlarged sectional view of the cigarette lighter llerValve forming the subject of this invention;

Figure 3 is a bottom plan view of a cigarette lighter having theimproved cigarette lighter iiller valve mounted thereon; and,

Figure 4 is an enlarged perspective View of the cigarette lighter iillervalve and the nozzle for attachment to a container made in accordancewith this invention.

Referring now particularly to the accompanying drawings, there isdisclosed a conventional cigarette lighter having an internally threadedfiller port 12. The cigarette lighter 10 is provided with the usualmechanism 14 for igniting a Wick. The cigarette lighter 10 is alsoprovided with the conventional packing 16 which is adapted to besaturated with iiuid for conveying the same to the wick of the lighter.

The cigarette lighter ller valve forming the subject of this inventionincludes a plug 18 which is externally threaded as at 20. The plug 18 isprovided with a radially extending ilange 22 at one end thereof which isadapted to engage the bottom of the cigarette lighter 10. A suitablegasket 24 may be disposed on the plug 18 in engagement with the flange22 for providing a seal between the flange 22 and the bottom of thelighter 10.

atent O Patented Apr. 3, 1956 The plug 18 is provided with alongitudinally extending bore 26. Conical recesses 28 and 30 areprovided in the opposite faces of the plug 18 and intersect the bore 26.The conical recess 28 is adapted to be disposed interiorly of thelighter 10 and the conical recess 30 is adapted to be disposedexteriorly of the lighter 10.

The inner end of plug 18 is provided with a longitudinally extendingsleeve 32 which is concentric with the bore 26. Received Within thesleeve 32 is a cage 34 which extends inwardly into the lighter 10. Thecage 34 is provided with a plurality of apertures 36 in the side wallsthereof. The inner end of cage 34 is provided with a hollow extension 38of reduced diameter in comparison to the main body of the cage 34.

A check valve comprising a ball 40 is adapted to be seated in theconical recess 28. A coil spring 42 is disposed within the cage 34 andengages the ball 40 at one end and the junction of the extension 38 withthe main body 34 of the cage forms an abutment for the other end of thespring 42. Thus, the spring will resiliently urge the ball 40 intosealing engagement with the bore 26. When fluid is forced through thebore 26 the pressure thereof will unseat the ball 40 allowing the fluidto flow into the cage 34 and through the apertures 36 into the packing16.

In order to prevent the loss of liuid when transferring the tluid from acontainer to the lighter a special nozzle is provided for seating withinthe conical recess 30. The nozzle is formed of a body 44 having alongitudinally extending bore 46 therein. One end of the body 44 isprovided with an enlarged aperture which is internally threaded as at48. This aperture is adapted to receive the nozzle of a container 50 ofsuitable lighter fluid. The other end of the nozzle is provided with atapered face complemental to the conical recess 30. The portion of body44 having the tapered face thereon is preferably formed of an insert 52of ilexible material. Thus when the nozzle is inserted in the conicalrecess 30 the flexible material will form a seal with the conical recess30 preventing the loss of iluid.

If desired, the entire body 44 can be formed of the resilient material.The nozzle of the container 50 may be applied to the conical recess 30.The extension 3S is provided with elongated slots 54 extending from thefree end thereof. This will render the extension 38 resilient so as tofrictionally retain spare ilints 56 therein for storage purposes.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly, all suitable modifications and equivalents may be resortedto, falling within the scope of the appended claims.

What is claimed as new is as follows:

l. An integral detachable lighter filler valve assembly for use with alighter having an internally threaded lilling port in communication witha fuel compartment containing a fluid absorbing material, said valveassembly including a plug element including on opposite sides thereofconical recesses intersecting and in communication with a longitudinalbore, an annular flange portion extending from one of the sides of theplug surrounding one of said conical recesses for sealing engagementwith the lighter, said one recess providing a readily available fillingopening, said other conical recess defining a valve seat for a ballcheck element, a longitudinally extending sleeve, concentricallydisposed about said other conical recess, an elongated cage element forextending into said lighter and fiuid absorbing material containedtherein being secured to said sleeve at one end and including a reduceddiameter ange portion at the other end, a plurality of longitudinallydisposed apertures extending substantially along the length of said cagefor distributing fuel therethrough, a ball check engageable in saidother conical recess, a compression spring interposed in said cagebetween said ball check and said reduced diameter ange portion of saidcage, and meansadapted to sealingly engage said one conical recess forapplying fuel under pressure against said ball check for permittinglongitudinally pressure distribution of fuel through the lighter when inan upright position whereby release of said pressure permits readysealing of the ball check in said other conical recess, said cageelement including at the reduced diameter portion an annular sleevehaving portions defining a plurality of longitudinal slots forresiliently and frictionally engaging spare flints retained therein.

2. A lighter filler valve as set forth in claim 1 wherein said meansadapted to sealingly engage said one conical 4 recess includes a nozzleelement having a longitudinal bore extending therethrough, and includingon one end a conical tip conforming to the coniiguration of said oneconical recess for sealing engagement therein.
